     #content1. text + 100px of red content (#content2) is too tall to fit
     beside #float2. It would at this point fit beside #float1, but that would
     cause the width to increase again, and the spec says layout always moves
     forward. */

  /* Trying to fit #container beside #float3 causes the rest of the red content
     (#content2) to disappear. */

<p>You should see the text "no red" to the left of the third float and no red.</p>
